I wasn’t aware of them, probably because I was looking for a general concept for restrictions, and the titles of these pages only talk about _access_ restrictions. The third link seems to be what I was looking for, a page where all suggested solutions are (planned to be) presented and discussed (like the „Linienbündel“ page). Interestingly, on the discussion page of second link, the array syntax is also mentioned, along with some other interesting proposals. I see that a lot of discussion has already been done, but it seems to me that no one has really collected the results on the Wiki yet. > Array syntax or similar options have indeed been discussed, too, e.g. > over there: > http://wiki.openstreetmap.org/index.php/WikiProject_Germany/Workshops/Linienbündel > http://forum.openstreetmap.org/viewtopic.php?pid=13730#p13730 > (German wiki/forum) I knew the „Linienbündel“ page, it was actually what I was talking about when I mentioned using relations for pavements. > Imo, all of these cases could be solved by using individual objects, > most notably relations.

It's not inherently superior to individual objects, though. I see my proposal as a way of conditional tagging that doesn’t mix up the meaning of key and value and that doesn’t need a change of the current tagging behaviour (in contrast to other solutions). You could in fact see it as a workaround for the fact that grouping tags is not possible (which in my opinion is a good thing, but editors could display indexed tags as if they were grouped), but I don’t think that a better relation support could solve problems with tagging complicated restrictions. -- Candid Dauth Rotbachstr. 9 88433 Schemmerhofen-Ingerkingen Germany http://cdauth.de/ _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
